Solar Cell Patch Antenna
This arrangement not only allows for total exposure of the solar cells to sunlight 100 insolation but also improves antenna.
Solar cell patch antenna. For example some patch antennas are approximately half a wavelength on each side. The original feature of a solar cell dc current generation remains but additionally the cell is now able to receive and transmit electromagnetic waves. Figure 5 27 shows an example of a patch antenna. The of received power can be improved by 1 2 1 4 times when using the.
A couple of e patches antennas have increased the bandwidth 33 and the directivity up to 20 dbi. These units may then be replicated as desired to create a structure. The main disadvantage of these antennas is their relatively large size compared to other types of antennas. A circularly polarized cp patch antenna loaded with a metasurface which is realized with a lattice of 4 4 square solar cells is presented.
The solar cell antenna is allowing harvestingdifferent wireless applications. The radiating patch element of a planar antenna is replaced by a solar cell. The antenna is composed of a slotted circular patch sandwiched between the metasurface and the ground plane. Patch antennas come in various shapes and sizes and consist of a patch of metal directly above a ground plane.
As technology has been advancing rapidly an idea emerged to integrate the antenna and solar cell into monolithic building block units.
